Revert "Tightly pack LinkedUniform by using int16_t" This reverts commit 152cf62b38874238095a91307e4ea9bcdedf8f46. Reason for revert: Suspect cause of failure in for several Linux MSan Tests, e.g. https://ci.chromium.org/ui/p/chromium/builders/ci/Linux%20MSan%20Tests/42403/overview https://ci.chromium.org/ui/p/chromium/builders/ci/WebKit%20Linux%20MSAN/22174/overview https://ci.chromium.org/ui/p/chromium/builders/ci/Linux%20MSan%20Tests/42403/overview Original change's description: > Tightly pack LinkedUniform by using int16_t > > There is a check of vector size when we link uniforms and the maximum > vector size is 4096 due to we clamp the maxUniformBlockSize to 64KB. In > reality, if we exceeds this number, program link will take really long > time and then hit failure. So there is no real need to keep all the > variables in 32 bit integer. This CL changes to 16 bit integer. Further, > sh::BlockMemberInfo and ActiveVariable data members are embeded into > LinkedUniform struct as well so that the unused variables can be removed > and data can be tightly packed. This also makes LinkedUniform easier to > maintain as a simple struct with basic data types. With this change, > LinkedUniform size is reduced from 108 bytes down to 60 bytes, 48 bytes > reduction. Given some apps has 200-ish uniforms, this CL reduces 48 > bytes x 200 = ~9K memory just for uniforms per program (which goes > through hash compute and decompression and file reads). > > Bug: b/275102061 > Change-Id: I7fae20f5b75f3239305e2094a992e3040b8c8e4c > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4754133 > Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> > Commit-Queue: Charlie Lao <cclao@google.com> Bug: b/275102061 Change-Id: Id344e306307553731097f06edafc40bfeb73ff80 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4780494 Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Geoff Lang <geofflang@chromium.org>
